I have to admit: the only time I don't like my ebike is when I am riding up the hill from my house (varies easy to moderate) and I come up behind a group of 'proper' cyclists sweating their way up the hill. I can't NOT overtake as I don't want to wait, but I'm embarrassed to do so. The first time it happened, I whizzed past and just shouted "It's OK, I am cheating!". Now, I man up, turn the assistance off (so no tell-tale whine from the rear hub) and make a humongous 30-second effort to pass under my own steam, before reinstating the power when out of earshot. As I am riding something weighing about 22 kg, this takes it out of me for the next half-hour. Good exercise, I suppose.
You need a "Poseur pass"
Pedal as fast as you can, full power, build up a head of speed, switch off power then sedately bimble past.....
Then take the next turning before you collapse!
